Description

The utility model relates to the design of mass transfer plates for gas (steam) - liquid systems designed for absorption, distillation and can be used in food, moonshine, chemical, petrochemical and other related industries.

Known CAP plate according to the patent for invention RU No. 2602113, (published: 10.11.2016 Bull. No. 31). The cap plate consists of a base in the form of a disk, bubbled caps made in the form of cylindrical or conical glasses with slots in their lower part, overflow pipes and a water seal. Lamellar ribs located in the horizontal plane are made on the caps, and the ribs of adjacent caps overlap each other and are located in different planes, forming, when mutually overlapping, labyrinth passages for the product being processed in the apparatus, and the ribs of adjacent caps do not touch the surfaces of other caps. Each cap of the plate has at least one lamellar rib made in the form of a ring or a hexagon, inserted through its central hole onto the cap glass, the diameter of the central hole of the ring corresponding to the outer diameter of the cap glass in the place of its fastening on the cap, and the outer diameter of the ring does not exceed the distance to the adjacent contact element of the cap plate.

The disadvantage is the low degree of purification of the vapor.

Known RECTIFICATION COLUMN WITH CAP PLATES according to the patent for invention RU No. 2472565 (IPC B01D 3/16, published: 01.20.2013 Bull. No. 2). Distillation column, including a housing with technological fittings, plates with steam and overflow nozzles, as well as height-adjustable bubble caps, characterized in that the upper end of each overflow nozzle is fixed in the plate with the possibility of axial movement of the nozzle relative to the latter, and its lower end is equipped with a disc perforated disk, as well as a glass concentric overflow pipe and forming a water seal with it.

The disadvantage is the low degree of purification of the vapor.

The closest technical solution is a cap-type plate of column apparatus (PLATTERS CAP STEEL COLUMN APPARATUS. PARAMETERS, DESIGN AND DIMENSIONS (OST 26-01-66-86)). The cap plate consists of: the base of the plate; drainage partition; overflow partition; drain pipe; steam nozzle; visor pressure ring; ring; clamp; bracket; a pen; chipper; support stand; special hairpin; mounting bracket; special bolt; AC 10 cord GOST 5152-84; cap according to GOST 9634-81; nut in accordance with GOST 5915-70; washer according to GOST 11371-78.

The disadvantage is the low degree of purification of the vapor.

The objective of the technical solution is to increase the degree of purification of the vapor. It also provides reduced material consumption and improved ease of maintenance.

Improving the degree of cleaning is achieved due to the fact that the bubbler plate containing the base of the plate, overflow rod, cap, made in the form of a cylinder with slots in their lower part, according to a utility model, the base has a recess and a supporting edge in the upper part, in the upper part of the recess slots are made in the base, and a hole is made in the bottom of the base, in which the overflow rod is located, on the outer side of the plate base, hiding the protruding end of the rod, a cap is installed, holes are made in the rod, both sintering when the liquid in the plate reaches a predetermined level, it drains through the internal cavity of the cap, the slots of the cap are located above the level of the lower hole of the overflow rod, the plate is supplemented by an insert made in the form of a pipe segment, the insert is installed inside the base with a gap between their walls and has a supporting edge, which rests on the supporting edge of the base, slots are made on the insert from the side of the opposite supporting edge, the slots of the insert are located below the level of the slots in the base of the plate.

Slots of the insert can be made with the formation of a closed ridge at the end of the pipe segment.

The slots are evenly distributed over the cross section of the pipe section and the width of the slot is equal to the distance between two adjacent slots.

The number and shape of the slots of the base of the plate is designed in such a way as to achieve maximum steam throughput while maintaining structural strength.

The number of slots of the insert and their frequency are selected to create the maximum possible number of small streams of steam.

All elements of the bubbler plate are made of copper or stainless steel.

The essence of the utility model is illustrated by drawings, where:

in FIG. 1 shows a General view of the device;

in FIG. 2 shows a General view of the device in section.

The following notation is made in the figures:

1 - the base of the plate;

2 - insert;

3 - overflow rod;

4 - cap;

5 - screw.

The bubbler plate is assembled as follows. An overflow rod 2 is installed in the hole located at the bottom of the base of the plate 1, a cap 4 is put on the overflow rod 2 on the outside of the base of the plate 1, the cap has a hole for the fixing screw, the overflow rod is fixed with screw 5. Insert 2 is installed in the base of the plate 1.

Bubble plate works as follows. Gas and particles of liquid trapped by it move from bottom to top. Boiling of the liquid occurs and a mixture of vapors is released. They pass through the slots of the base 1 of the bubbler plate, where due to the presence of insert 2 in the form of a pipe segment with slots, the steam stream is divided into many small streams that interact better with reflux that accumulates on overflow rod 3 and sparges, while increasing the degree of cleaning vapor. The overflow cap allows you to maintain the level of phlegm, and excess phlegm merges through it.

It was established experimentally that the number of installed bubble trays in the distillation column allows to achieve an increase in the degree of purification of the obtained distillate.

The utility model provides an increase in the degree of purification of vapors. It also provides reduced material consumption and improved ease of maintenance.
